Answer:
3.1 m
Explanation:
Okay, to find the circumference of a circle the formula is c = 2 3.14 x r.
R represents the radius.
So, you are trying to find the radius of a circle not the circumference of a circle. We know what the circumference is (19.468).
Therfore you would multiply each answer choice by 2 then by 3.14.
3.1 x 2 = 6.2
6.2 x 3.14 = 19.468
19.468 = 19.468
So your answer is 3.1 m.
To double check all your math you would do this to each answer choice.
I hope that this helped! :)
